Ratings & Reviews

Made the most difference of any skin care product


I don't write many reviews; usually I write about product that I feel very strongly about one way or the other. And I feel pretty strongly about the peptide booster. I almost exclusively use Paula's products and have been for many years, and try to follow the recommended routines as closely as possible. Because of this, it can be difficult to isolate the effects of any one product since I believe they all do good things for my skin. However, I feel pretty confident in saying that I noticed a very significant difference a few weeks after incorporating the Peptide booster into my routine. I'm currently 48 years of age, and in the last 6 months, I had noticed a general loss of firmness and more pronounced marionette lines. It was actually making me feel quite sad. I'm almost finished my first bottle of the Peptide booster and have been using two drops, once daily. Since I have been using it, I have noticed a really significant improvement in how my face looks: my marionette lines have significantly improved but the appearance of firmness has basically reversed from what I saw before I started using it. One very telling sign for me came when I started noticing a 'shine' on my cheeckbone after I would wash my face, as though the skin was tighter than it had been. Again, I hadn't changed the way I wash my face or the products I wash with, and haven't added any other products to my skin care routine so I can only surmise that the Peptide booster is responsible therefore I highly recommend it.




New Must Have


I wouldn't normally review a product after only 4 days of use, but I already know I love this one and it works. I am 40 and luckily don't have a lot of lines, but I do have unevenness, sun damage, and dehydrated skin. This product goes on super light weight and is not oily at all. After just one use, I woke up to tighter (in the good way) and more even skin. It even has reduced my double chin a little because my skin is firming up. I will continue to repurchase this for sure.




Best product ever!!!


This product is nothing short of incredible!!! I've used PC for 20 years now and Paula's wonderful products have always gotten me compliments on my skin. Unfortunately, at 37 I am starting to get some fine lines and wrinkles...enter the peptide booster!!! Within 4-6 weeks I started to notice a dramatic difference in the lines on my forehead and around my eyes! I haven't been more pleased with a product since I last used Botox! Just one drop twice a day on my forehead and around my eyes and my skin looks 10 years younger! I can't believe it! Thank you Paula and her team!

My skin LOVES this


I tried this as a sample. Based on the description , I honestly wouldn't have purchased it myself but my skin loves it!! My skin is doing much better- clearer.. and I'm able to use bha now(gel, my skin doesn't like the liquid). mainly my issue is acne prone dry skin.. and I am 33 but really don't have any aging issues.. however I realized I should start preventing. I realized too that the moisturizer my skin loves in the winter (advanced recovery) also has peptides so maybe my skin loves peptides lol. I've tried other boosters and wasn't impressed. This one isn't oily but just soaks in, I put it all over, it helps my patchy flakey skin too. Only thing is honestly for the price I expected a bigger bottle.

Very happy


Normally I try lots of different skin care products, I've never found one I totally love or can't live without, it's hard to tell if they work or not. Well, this product is the exception. I love this serum, my skin is visibly brighter when using it. I'm 36 years old and have normal skin. I can't tell if it's softening my lines but my skin is definitely brighter and less dull when using it. I can't live without it now.

I add it to serums and my pores look better and my skin overall looks more moisturized.




Must have for all skin types!


I have combo, acne prone, sensitive skin and of course anti aging had always been apart of my routine. I'm 30 but my mother stressed the importance of skin at a very early age. I use the retinol booster, hyloronic booster, azylic acid, 8% BHA, resist toner, Sunday Riley cleanser and good genes as well as a drunk elephant mask. This booster is essential to this regime, especially on days that I don't use my retinol or aha's. My husband has severely dry skin so he doesn't use any retinols or "irritating" products and this gives him the anti aging results those products provide. This makes my skin soft, plump, fine lines less visible and over all improves the look and appearance of my skin. I've use PC for several years and love the products because I don't have to worry about fragrance, irritating ingredients, acne causing ingredients and they are just worry free all around. I put PC right up there with any other brand. Grab this booster, I believe everyone's skin can benefit.




Good Addition


As I get older (69 next month) my skin has gotten more sensitive. I can't use high concentrations of much -- Retinol, AHAs, etc. just make my face sore. I got this and added it to regimen. It is improving my lines, the big ones and the little ones. Also, my complexion appears smoother and more even. I'm very happy with this product. My routine uses all kinds of products from many companies; I use a little Tatcha, a little Dr. Denese and some Josie Maran. This gets five stars for making everything work better.

Youth in a bottle!


I use Retin-A at night so I need a gentle age-fighter during the day. This is IT. I added it to my routine three months back and it has made the most amazing difference. I use the Resist for oily skin toner and BHA day and night, adding this during the day as well as the Omega 3 serum. Top it off with either the Resist oil-free spf or Hydralight SPF 30, and I look 10 years younger than my 46-year-old self! It is pricey but I purchase whenever there's a 20% off sale (which is often). I've used PC products for years and it shows. The products keep getting better and better. I'm not brand loyal typically but I have never strayed from PC. For reference, I have aging, oily skin that's acne-prone and sensitive.

Nice Serum


As someone who needs to restrict or eliminate the use of retinol, vitamin C and niacinamide, some of the best anti-aging products are off limits to me. So my first praise for this product is that it contains none of those wonderful ingredients. The texture is super silky and lightweight enough that I do not have to concern myself with whether or not it's too much moisture for my constantly changing combo skin. I hate dropper bottles for skincare (although I guess I'm in the minority since they are so popular now) but this does come out of the dropper easily. I can consistently get out the three or four drops I use nightly. I usually mix it with a very boring lightweight moisturizer so I don't have too many "actives" on my face at one time. Oh the joy of having redness prone skin! I'm almost done with my first bottle; it has lasted over two months. It's pricey but I'll be re-ordering. I'd love it even more in a pump dispenser like like 1% Retinol booster that I wish my skin would tolerate!
